Decrement Field Value By 1, Using A Single Query
Dec 15, 2005
Hi,
I have a product table in Access, like this:
product_id | product_name | product_quantity
I need to be able to do an SQL update on this table to subtract 1 from the product_quantity field.
I could do this with two SQL queries (SELECT product_quantity, then subtract 1, then UPDATE table) but I'm sure there must be a way just to run one query which subtracts 1 from the field.
Does anyone know how to do this?
Any help would be fantastic, thanks!

I have set up a parameter query in Access 2003 that asks the user for the "Section", such as "Admin", "Accounting" etc.
I need them to be able to respond to the prompt with more than one section if they want- sometimes just one, sometimes two or three or four.
So they can get "Accounting" and "Admin" both in the records that are returned.
The code:
SELECT T_ElainesMaster.Section, T_ElainesMaster.Login, T_ElainesMaster.Workstation, T_ElainesMaster.NT, T_ElainesMaster.Barcode, T_ElainesMaster.[PC model], T_ElainesMaster.[Emp Name], T_ElainesMaster.[swap or not], T_ElainesMaster.[Exp Date]
FROM T_ElainesMaster
WHERE (((T_ElainesMaster.Section) Like [What section would you like to include?]))
ORDER BY T_ElainesMaster.Section;
Thanks!

Hey guys, my problem is this:
I want to run a query that runs off of two list boxes on a form. However, I want both these parameters to filter a single field in my query. Why I want to do this is I have several types of accessories made by several manufacturers, both included in the "Description" field. I don't want to include an entirely new field for manufacturer because it's only 4 out of about 5 items that need this.
Is there a way this can be done or will I be forced to include a manufacturer's field.
Thanks in advance
Nathan

Hi Guys, I'm new here and fairly new to anything indepth with Access.
I'm using Access 2003 and have a table which has a number of customer records. The two relevant fields are the CustomerID which is a simple integer and OrderDate obviously this is a date field!
What I need (to link in with the other forms) is a query that will return one record for each CustomerID it should be the most recent OrderDate.
I've had a few attempts and done a couple of searches but can't seem to find exactly what I'm looking for. If someone could point me in the right direction I'm happy to play with sample code and read up on bits other people have done (I tend to learn better that way) rather than just being given some code!
Thanks for any help you could can provide.

I am designing a database in Access 2010 to handle customer discounts. The problem I am facing is that the discount can vary by customer. One could be a straight percentage based on certain sales totals, even the percentages can vary by customer, and some customer discounts are tiered. I was hoping there was a way to handle all through one query, because there are so many variations, it would require several queries if I separate by each calculation available.
Is there a way to set up a table listing the customer and their corresponding calculation expression then running a query using that table and the sales data table to do all the calculations. Or is there another way to handle this level of complexity in Access? The end result I would like is one data set with each customer and their calculated discount.

I am trying to create a form with a button attached to each record that would allow the user to click the button and it would automatically open outlook and fill in the TO:, SUBJECT: and BODY: fields. Here is the code that I currently have:
Code:
Private Sub Command33_Click()
Dim strEmail As String
Dim strMsg As String
Dim oLook As Object
Dim oMail As Object
Set oLook = CreateObject("Outlook.Application")
Set oMail = oLook.CreateItem(0)
[code]...
There are two issues I keep running into:
1. This code opens outlook and populates all of the fields but pastes the email incorrectly. Instead of pasting just the email (email@email.com) it pastes the html tags as well (email@email.com#mailto:email@email.com#) which means that the user would have to delete everything between the #'s in order to send the email every time.
2. I currently have the email BODY pulling from a table but this obviously limits what I can do. I would like to simply encode the BODY within the VBA code. The setup I am looking for is:
one paragraph
a blank line
a hyperlink to a website
a blank line
another paragraph

I am trying, and failing quite spectacularly to create a single query that will contain multiple expressions on the same field.
Please see attached jpg for example.
SQL: SELECT Count(StockData.status) AS FaultyPCs
FROM StockData
HAVING (([StockData].[Status] In ("Waiting Repair") And [StockData].[DeviceType] In ("Thick PC")));
What I want to be able to do is then add additional expressions to filter and count in the same way for "Thin PC" "Thin Laptops" "Thick Laptops" and so on.
But when I add one of these expressions to the next column in the builder, it seems to apply itself to the expression to it's left, causing that one to now give a result of 0.
Is there a way of separating one from another or do I have to create a separate query for each expression and then use another query to pull them all together (as I have done in another situations - but this will involve creating probably 20 separate queries.

I'm creating a database for my wife to use in her work, one of the fields is dates visited and the user should enter "00/00/0000, 11/11/1111, 22/22/2222, 33/33/3333" in this format. The field is a large text format because there could be anything from 1 date to hundreds. What I need to be able to do is in my query I need to enter 2 dates and have access return a how many dates exist between those 2 date values. eg It will pop up a box asking for start date and then another asking for end date and then it has to return the count total of how many dates exist between those two date values. I don't know VB and have had only basic training in Java and C# none of which involved Access. The only way I can think of doing it is to have access count the number of commas within the date field required but I don't know the formula required assuming it can even be done.

Basically, what's the best practice or how do we store a query's value into an array then checking what the max or min value is and how to check if let's say "4" is in the array?

I have a datase that has the following fields.
Name
Comment1
Comment2
I have about 36 names and each of those names appears anywhere from 2 7 times each. Each name entry has a comment1 and a comment2.What I would like to do is create a form that allows me to choosea name and the display the comments 1 and comments 2 in text boxes.
I have made the form to allow me to choose a name and it shows one of the comment1 and one of teh comment2 in the adjacent text boxes as planned but, I want all the comment1s for Bob to show in the text box for comment1 and all of the comment2s for Bob to show in the Comment2 text box.I believe I need to concatenate the results in the comment1 and comment2 boxes, but I do not know where or how I would do that.

Hi all. I'm working on a temporary database (Access 2003) for work until we get our system validated. Is it okay or acceptable to have a single-field table or do I need to throw an autonumber on there for the key? I really just need this table to populate a combobox/listbox in the form. I don't want to to use the "OnNotinList" with the combobox so I need to store them somewhere. Thanks!

REPOST from Design Area
Hello all,
I hope that the following explination of my problem in clear...
I have a table with a series of dates in individual fields: Day1, Day2, etc.
What I would like to do now is to combine those into another query/table where the dates are all in one field.
ie:
Original Table
[Day1] March 1
[Day2] March 2
[Day3] March 3
New Table
[Date] March 1, March 2, March 3.
Can you help me figure out how to accomplish this? I greatly appreciate your time and sharing of any thoughts that you have on this situation.

Hi, this is my first post here.
My question is this: I am creating a database for a student survey. Some of the questions may have multiple answers.
For instance, question 2 reads:
"What location/time are you taking courses (select all that apply)"
and the possible answers are:
1)Daytime/Oakland
2)Evening/Oakland
3)Saturday College
4)BC
- Where a student could be taking classes at multiple locations or times. I am completely lost as to how to set this up. I have tried to set the properties for the field on the form to accept multiple responses, but of course, these do not save to the table and so it's completely useless.
Thank you in advance for your help!!!

I want to be able to perform an AND search on a field where both specified values must be present for an item to be selected.
I have a table with some properties of items. Each record in the table is for a specific item and one of its properties. Say for instance that I want to list the items that are described with both "red and green". Assume that there are entries for widgetA to widgetG with colors "red, blue, yellow, purple" and widgetB and widgetE also has the property "green" in addition to the others ... the query should return widgetB and widgetE only.
I tried to use MSAccess 2003 query builder but cannot get the AND result to work. I switched to an OR and verified that the two values I am searching for do exist for two items in my table.
Here is the SQL statement that did not work.
SELECT Properties.PropertyIndex, Properties.HerbOilLink, Properties.PropertyTypeIndex, Properties.PropertyDescriptionIndex
FROM PropertyType INNER JOIN Properties ON PropertyType.PropertyTypeIndex = Properties.PropertyTypeIndex
WHERE (((Properties.PropertyDescriptionIndex)=80 And (Properties.PropertyDescriptionIndex)=15));

I am a struggling low level user and any help will be appreciated. I’m trying to get data out of an old database and into a new one. The following addresses will give you some idea as to what my problem is. :confused:
I would like to break up the following single field address (Note the different pieces of data.
Washington Blvd 1407
Jefferson ST 234 N
Benjamin Ave 2105 N #1
Lincoln Cir 1407 N Unit 201 (Notice the space after Unit)
and have it look like this
Field one: 1421
Field two: N,S,E or W
Field three: BENJAMIN ST, Ave, or etc
Field four: Anything left over
If you can help, please talk very slow and loud cus I'm old and not too bright. I have limited experience with Instr, Mid, Left and Right functions, but can never seem to get them to work in a SQL statement I think I need to use multiple append queries but I’m guessing and then how do I get all the pieces into one table. :o
Thank you in advance

Sorry for this totally stupid question but my memory is just not what it once was.
I need to separate one field into two, in a table that was imported from excel
Basically it has a size and a unit in each field
Example:
24.67 sy
26.84 sf
Thanks in advance for jogging an old man's memory.
I want to do this in a query not code if possible I remember something about a formula you can enter into the update to box in a saved query.

To anyone who can help,
I have created a function that loops through an amount of records and concatenates them into a single comma-separated string. What I would like to do is concatente the values into a list. Instead of:
value1, value2, value3
I would like to see
value1
value2
value3
This needs to be in a single record only. The code I am using is:
----------------------------
while not rec.eof
string = string & ", "
rec.movenext
wend
string=left(string,len(string)-2)
--------------------------------
Thanks for all your help. I have tried to insert char(20), but this only seems to work in Excel. Access gives me invalid char symbol.

I have question regarding multiple choices fields. I would like to store constrained but multiple values in a single field. I used the assistant to create the multiple choice field in the table, but I'd like to have it displayed in my form with check boxes (more readable in my tabular form) instead of drop down list. Is it possible ...

Hi, thanks in advance for any help you can offer. I've got a table that has
Date
Time
Tag ID
Power Level
throughout the day a computer listens to several tags (transmitters) and records the power level of the signal generated by the tag each 3 seconds. What I'd like to do is build a query that gives the Date, Time and Maximum Power level reading for each tag ID. I only want 1 record per tag per day
I've tried using "group by" and max in the query but this gives me all the times throughout the day.
anyway, thanks again for looking
cheers, Shaun

I have a table of every reading of every electric meter. This history goes back a couple of years.
Field1 = date
Field2 = Meter#
Field3 = Single digit code identifying method of reading
The same meter is read multiple times in a year. The number of readings in the database is 1 or more (no limit).
I want to create a single line of text in 1 field that shows a history of the reading method of a particular meter.
Reading method translations
A=Radio Frequency
B=Manual
C=Not Read
X=Estimated
Here's a sample of what I would like to see .....

I have a query that displays all records. I need it to limit based on multiple criteria in a single field. I.E... instead of all employees from every section, I just want it to display employees from section A, C, D, F one time and next time maybe go with section B, C, D. For some reason the solution eludes my little brain.

Hello all,
I am sure this must be simple, but I can't get my head around it.
I have a query that looks at client bank account numbers, and finds duplicates.
There are a LOT of duplicates, because we have several accounts for the same person.
What I would like to do is find all the records where the account number and sort code match, but where the account NAME is different.
I am trying to find any records where the same account number is being used on more than one account.
All the fields are in a single table.
This is what I have so far, which just finds duplicate sort codes and account numbers;
SELECT CPL_ACCOUNT.ACCOUNT_NUMBER, CPL_ACCOUNT.SORT_CODE, CPL_ACCOUNT.BANK_NAME
FROM CPL_ACCOUNT
WHERE (((CPL_ACCOUNT.ACCOUNT_NUMBER) In (SELECT [ACCOUNT_NUMBER] FROM [CPL_ACCOUNT] As Tmp GROUP BY [ACCOUNT_NUMBER],[SORT_CODE] HAVING Count(*)>1 And [SORT_CODE] = [CPL_ACCOUNT].[SORT_CODE])))
ORDER BY CPL_ACCOUNT.ACCOUNT_NUMBER, CPL_ACCOUNT.SORT_CODE;
Thank you!
